Find the area and perimeter of the circle with the following :

Radius= 2.8 cm 

Advertisements

Solution

Area of the cirde = πr

`= 22/7 xx 2.8 xx 2.8`

= 24.64 cm2

Perimeter of the circle = 2πr

`= 2 xx 22/7 xx 2.8`

= 17.6 cm

Therefore, Area= 24.64 cm2 and Perimeter= 17.6 cm

  Is there an error in this question or solution?
